Clinical Study to Assess the Safety and Efficacy of the SpectraCure P18 System

Open-label Clinical Study to Assess the Safety and Efficacy of the SpectraCure P18 System (Interstitial Multiple Diode Lasers and IDOSE® Software) and Verteporfin for Injection (VFI) for the Treatment of Recurrent Prostate Cancer

Source: ClinicalTrials.gov · Last updated 1 May 2026

Brief summary (registry, in English)

The rationale for the study is to obtain safety and efficacy data as well as to establish dose parameters for the SpectraCure P18 System with IDOSE®, with verteporfin for injection (VFI) as photosensitizer for the treatment of recurrent prostate cancer.

Criteria the registry did not label

  • Gleason score ≥ 8 at initial diagnosis
  • Less than 1 week since surgery (excluding minimal procedures, e.g. vascular access device insertion)
  • Concomitant infection
  • Subjects with other severe concurrent disease that in the judgement of the investigator would make the subject inappropriate for entry into this study

  • Subjects with a history of CTCAE v4 grade 3 or greater or persistent (\>1 separate episode or symptoms lasting more than 3 months after initiation of medical intervention) grade 2 proctitis attributed to radiation.
    • Phase 2 Inclusion Criteria:

  • Less than 1 week since surgery (excluding minimal procedures, e.g. vascular access device insertion).
  • Concomitant infection.
  • Subjects with other severe concurrent disease that in the judgement of the investigator would make the subject inappropriate for entry into this study.
